1. A composite comprising
I a prepreg made of a solid mixture of a reactive synthetic resin and a reinforcing material in the form of textile or of fiber and optionally conventional additives in the form of an optionally rolled-up, continuous web and II a removable release film comprising a multi-layer structure made of
a) directly adjoining the prepreg web, a release layer composed of at least one thermoplastic homo- or copolymer of α,β-unsaturated olefins, a waxy compound as release additive, and optionally conventional other additives and auxiliaries,b) optionally an adhesion-promoter layer,c) a layer composed of at least one thermo-plastic polyamide homo- or copolymer,d) optionally an adhesion-promoter layer,e) a release layer which is composed of at least one thermoplastic homo- or co-polymer of α,β-unsaturated olefins, and which has a release coating based on a cured polysiloxane, or as alternative to the layer e) a sublaminate made ofe′) a layer composed of at least one thermo-plastic homo- or copolymer of α,β-unsaturated olefins,f) a lamination adhesive layer, andg) a release layer which is composed of at least one thermoplastic polyester and one waxy compound as release additive, and optionally conventional other additives and auxiliaries, org′) a release layer which is composed of at least one thermoplastic polyester, and which has a release coating based on a cured polysiloxane as alternative to the layer g) of the sublaminate. |
